4 Claims.

This invention relates to door locks and the object of the invention isto provide a lock which may be used on the doors of automobiles,airplanes, boats, and analogous vehicles, or on the doors of buildingsand the like.

A further object of the invention is to provide a door lock of thecharacter mentioned which may be operated from either side of the doorand which may be operated from the inside of the door for locking thedoor against being opened by an unauthorized person from the outside.

A further object of the invention is to provide a lock of the characterabove mentioned which, while the same may be locked from inside the doorwithout resort to a key, a key will be required for unlocking the doorfrom the outside thereof.

Referring to the drawings by reference numerals it will be seen that inthe preferred embodiment thereof the door lock comprises a suitablecasing l divided into a pair of compartments 2 and 3 respectivelythrough the medium of a partition plate 4. Provided in the compartment 2are upper and lower guide members 5 between which as clearly shown inFigures 2 and 7 is slidably mounted a locking bolt 6 that is normallyurged to a projected position through the medium of a suitable springdevice 1.

For the inside of the door lock is a handle 33 which as best shown inFigure '7 is secured to one end of a stud 3! journaled in a suitablebearing 32 provided therefor at the inner side of the easing l. The stud3| has a squared end that extends into the compartment 2 and on saidsquared end there is provided a male head 30. Head 30 has suitablyassociated therewith a lug 38 which as shown in Figure 5 moves intoengagement with a lug 42 on the bolt 6 incidental to a swinging movementof the handle 33 in a counter-clockwise direction for retracting thebolt 6 from the inside of the door with which the lock is associated.

Further in accordance with the present invention there is arranged forsliding movement in the compartment 3 a slide block 8 that is normallyurged in one direction through the medium of a suitable spring device 9.

As clearly shown in Figure 6 slide block 8 has secured at one sidethereof through the medium of bolts 2 an abutment block ii that operateswithin a channel l0 provided therefor in the bolt 6. V

In this connection it will be noted that the partition 4 is providedwith a slot 4a to accommodate the bolts I2.

Mounted for vertical sliding movement in the compartment 2 is a slideplate l3 having a reduced lower end that works vertically through a slotl4 provided in the bolt 6 adjacent one end of the channel ID. The slideplate I3 is normally urged upwardly through the medium of a member l5preferably of the shape and construction shown in Figure 16 and whichmember is provided with pintles l6 journaled in the apertured lugs ll ofa bracket l8 suitably secured in the 7 ber l5 has a part thereofengaging in a notch 20 in the upper portion of the slide 3 as shown inFigures 10 and 11 for transmitting movement of the member l5 tothe'slide l3.

In Figure 10 the member i3 is shown in its raised position and asshownin Figure 6 when the member I3 is in raised position it provides Thuswhenthe' an abutment for the block ll. member 3 is in raised position itwill be seen thata sliding movement of the block 8 towards the right inFigure 6 will cause the block H to :abut the member l3 'so that themovement of the block 8 in the direction indicated will be transferredto the bolt 6 for retracting the latter.

For moving the slide block 8 in the direction above referred to forretracting bolt 6 there is provided at the outer side of the door orlock casing a handle 23 that has an end portion pivoted as at 24 withina suitable recess R provided therefor in the outer wall of the lockcasing I. At the pivoted end thereof the "handle 23 is provided with anintegral projection or dog 25 which engages a notch 26 formed at one'endof the block 8. Thus it will be seen that with the slide l3 in itsraised position an outward'swinging movement of the handle 23 to theposition shown in Figure 6 will ina manner just explained result in aretraction of the bolt 6.

From the above it will be seen that through the medium of the handle 33bolt 6 may be retracted from the inner side of the door and through themedium of the handle 23 bolt 6'may be retracted r from the outer side ofthe door.

For securing the bolt 6 against being'retracted by manipulation of thehandle'23 there is pro vided on the male head30 a lug 31 which, when thehandle 33 is swung from the position shown .inFigure'Z to the positionshown in Figure 4, will engage an extension 35 of them'ember |5 forcausingthe' member l5 to move downwardly thus causing the slide plate|3to move downwardly. In this connection, and as shown in Figure 4, itwill'be noted that as the lug 31' engages the extension 35 of' member I5forforcing the latter downwardly against the action of spring l9 lug 38associated with the head'30m'oves upwardly into engagement betweenspring jaws 39 suitably mounted in compartment 2 for securing the bandle33 in the position shown in Figure 4.

' When the'member i3 is caused to'move downwardly in the manner justmentioned the slot or notch Z'I-in'said member will align with thechannel In so that the member l3 will now offer no Figure 2.

resistance to the block n. Thus with the mem-.

ber l3 in the lowered position it will be seen that handle 23 may bemanipulated for sliding the 7 Also in accordance with the presentinvention there is suitably mounted on the outer cover plate of easing akey-controlled lock 21 which includes among other parts a key-operatedbolt 28 that extends through partition 4 into the compartment 2. On thesquared portion of the bolt 28 is a female head member 29 which receivesin the socket portion thereof a part of the male head 30 as shown inFigure '7.

In connection with the above it will of course I be understood thatmember 29 rotates with the bolt 28 relative tothe head 30. Member 29isprovided with an integral lug 4| as shown in Figures 2, 4 and 5. c a

It willthus be seen that when it is desired to set the look from theouter side of the door to prevent retraction'of the bolt 6 the key 4|lisinserted into the lock 21 and. the bolt 28 rotated in a clockwisedirection; This will result of course in head 29 rotating with the boltfor movingzthe lug 4| associated with the head into engagement with theextended end 35 of the member l5. Thus lug 4| engaging said end 35 ofmember l5 will cause the latter to move downwardly against the action ofspring l5 for placing the slide 3 in the position shown in'Figure 11.

As previously pointed out with the slide |3 in its lower position handle23 may be manipulated for moving the slide 8 against the action ofspring 9 without in any way effecting a retraction of the bolt 6. 1

For locking the parts shown in the position in Figure 5, and to whichposition they were moved incidental to a turning of the key 40 in thelock 21 as just described, there is suitably mounted in.

and associated parts in the position shown in With the head '29'lockedin the position shown in Figure'5 member l5 will be held in the down-Ward position shown in'Figure 5 so that as just mentioned the assemblyis locked in a manner to preclude an opening of the door, or in otherwords a retraction of the bolt 6 by manipulating the handle 23 at theouter side of the door. Obviously, to unlock the door from the outerside thereof key 48 is turned in a reverse direction, or in acounter-clockwise direction causing the head 29 to move in acorresponding direction from the position shown in Figure5 to theposition shown in Figure 2 thus permitting the member l5 to moveupwardly under action of spring l5 for raising the slide plate I3 sothat the same will now present an abutment to the abutment block 'i l.Upon "return of head 29 to the position shown 75 in Figure 2, catch 43will engage the socket 44a as shown in said Figure 2 for locking thehead 29 in the position illustrated in said figure.

A bearing bracket 36 depends from the top of the compartment 2 and isprovided with an opening 36 which accommodates the cylindrical part ofthe head 30 as shown in Figure '7. In one edge thereof the bracket 35 isprovided with a notch 36a, for the purpose of allowing lug 31 clearancewhen the inner handle is used for retraction of bolt 6.

Since the manner in which the device operates was pointed out in thedetailed description of the parts it is thought unnecessary to again setout in detail the operation. Suffice it to say that a lock constructedin accordance with the present invention may have the bolt thereofretracted from either the inner side or outer side of the door withwhich the lock is associated, or said bolt may be disconnected from theoperating means therefor at either the inner side or outer side of thedoor to the end that a substantially fool-proof lock is provided.
